  • Reading from a file into an array in c

    - by NaNa21
    My file contains a series of numbers (integer, float, integer, float ....), each written on a separate line. The numbers of columns are different from one line to another i.e. 1 2.45 3 1.75 5 3.45 7 2.55 9 3.25 6 1.75 4 3.55 6 2.55 9 2.45 The program should read the contents of the entire file and place the data into an array of type float with an entry for each line. Here is my basic solution, but this is only suitable if I have fixed no of columns. float Read(FILE *pFile) { char line[50]; char letter[5]; fi = fopen("file.txt", "r"); while (fgets(line,200,fi)!=NULL) { sscanf(line,"%f %f %f",&a[i], &a2[i],&a3[i]); printf("%2.0f %2.5f %2.0f\n",a[i],a2[i],a3[i]); } fclose(fi); return a[i]; } Please HELP.

  • Why is iPhone 5 briefly Letterboxing and displaying Default.png in Cocos2d?

    - by The Learner
    I have [email protected] which loads fine. However, (on the actual device) after it shows the iPhone 5 then displays Default.png, in letter box mode. It then loads the 1136 × 640 px Title Screen - which is fine and what it's supposed to do. I'm using the default Cocos2d HelloWorld template. I haven't changed anything in the plist or otherwise. Any ideas? Why does it load the Default.png and how do you fix this? Thanks. In the IntroLayer we have -(void) onEnter if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone ) { background = [CCSprite spriteWithFile:@"Default.png"]; background.rotation = 90; } Which is why Default.png is showing up. How do you keep showing [email protected] if you are using the iPhone 5?

  • do you need captcha validation in newsletter subscription?

    - by user354051
    I am using a custom captcha php script along with news letter scripts to let users subscribe using an email id. The method of registration is based on jQuery.post command. My question is that am I really safe If I remove the captcha validation from my subscription script. The subscription is simple. For example mydomain/[email protected] The subscribe.php is called along with email as parameter using jQuery.post command. I am new to web programming stuff and don't have much idea about spammers in conjunction with above scenario. Any advise would greatly be appreciated. Thanks

  • Send data over telnet without pressing enter

    - by Matt
    I've recently started messing around with Java sockets and telnet... I want the user to be able to connect to the server, just type a letter and have it sent to the server, without pressing enter to send it. I'm sure there's no way for the server to set this up, but maybe telnet has a parameter or something which could allow this? Maybe if I got the user to type stty cbreak or stty raw before running telnet, this would work? (UNIX only, I know!) If I can get telnet to do this then it saves me having to write a special client just for this feature...

  • Vim plugin only works when file is provided as arg to launch command

    - by nsfyn55
    I am using the plugin java_getset.vim. The issue is that the plugin's commands are only available when I launch vim with the file as an argument. user@machine~: vim myfile.java If launch vim and use command-t or NerdTree to open the file in a buffer the plugin's commands are not accessible. All the filetype detection stuff is configured and working(I have syntax highlighting and indentation). The plugin source appears to be written to the letter according the the vim docs for a filetype plugin. Can anyone help me understand what changes a can make so that I can use this plugin in conjunction with Command-t?

  • Problem in the Android documentation

    - by Nick
    Hi all, This is my first post ever -- I love the Android SDK (been at it for a week), but I did notice a small typo in the official documentation that needs correcting. Not sure if this is where I post it, but on this page: http://developer.android.com/reference/android/os/CountDownTimer.html within the example source code, the source says "CountdownTimer" on line one when it should say "CountDownTimer" (notice the capitalization of the letter "D"). An easy fix for one with programming experience, but the code as written will not compile, which could be confusing for someone using this code for the first time. Is this where documentation bugs are submitted, and if not, where should I go to request the fix? Thanks all!

  • regular expression "(?<!^)(?=[A-Z])"

    - by imad
    I spent like three hours trying to understant how does "(?<!^)(?=[A-Z])" works to split at tring according to capital letters i.e. string[] s = Regex.Split("TheWorldWithoutStrangers", "(?<!^)(?=[A-Z])"); How does it work !! I do understand what is the meaning of each char in the above expression, but I do not get how does it work together. why "(? < !^)([A-Z])" doesnot work ? it means that whenever you find a captial letter that is not after a new line, then split, am I right ?

  • equivalent to getch(), mac/linux crash

    - by acidzombie24
    Hey guys. So I am using getch() and my app crashes instantly. Including when doing: int main() { getch(); } I can't find the link but supposedly the problem is, it needs to turn off buffering or something strange along those lines and I still want cout to work along with cross platform code. I was told to use std::cin.get(), but I'd like the app to quit when a key is pressed, not when the user typed in a letter or number then press enter to quit. Is there any function for this? The code must work under Mac (my os) and Windows.

  • A puzzle coded in ASCII [closed]

    - by user1905398
    I'm asking this question again because it is valid: "How do I convert this: M D Y z M D Y w M D Y z M D Y x M D Y z M D Y w M D Y z M D Y w M D Y z M D Y w M D Y z M D Y x M D Y z M D Y x M D Y z M D Y w into a letter? I have 272 constructed just like this one that I need to convert to form the message in a mystery I'm trying to solve. Thanks!" It is very difficult to include all 272 strings with each one having 16 sets of 4! There wouldn't be enough room in this post for that, so I just put the first of the 272 strings. To hopefully clarify, this is a puzzle. The puzzler put his 272 word message in ASCII. Since there is no online converter, I put the question out hoping to get some help.

  • phablet-flash aborting while installing Ubuntu Touch on Nexus 4

    - by Till B
    I have a Nexus 4 with Android 4.3 installed and I want to flash it to Ubuntu Touch. My system is Ubuntu 12.04, running inside a virtual machine on Mac OS 10.5.8. To use the VM, I opened an NAT bridge and forwarded port 5037 for adb, I can see the Nexus with adb and e.g. use the adb shell into it. USB ports are also forwarded to the VM. I follow these instructions to the letter. My bootloader is unlocked, just as it was described in the instructions. Now I encounter different issues, when executing sudo phablet-flash ubuntu-system --no-backup. On the first run, it got stuck in this state: INFO:phablet-flash:Decompressing partitions/recovery.img from /home/till/Downloads/phablet-flash/imageupdates/pool/device-5ba3031cb0d6fc624848266edba781e3e821b6e1e8dd21105725f0ab26077d0a.tar.xz INFO:phablet-flash:Restarting device... wait INFO:phablet-flash:Restarting device... wait complete INFO:phablet-flash:Booting /tmp/tmpMSN8bm/partitions/recovery.img < waiting for device > downloading 'boot.img'... OKAY [ 1.772s] booting... OKAY [ 0.005s] finished. total time: 1.779s INFO:phablet-flash:Waiting for recovery image to boot The following happened: around the line "INFO:phablet-flash: Restarting...", it rebooted into the bootloader. The bootloader shows only for two seconds, then the screen goes off and the phone stays off. But I do notice, that the screen is not off - it is just black, but the background light is on. If I wait long enough, phablet-flash aborts with ERROR:phablet-flash:Wait for recovery expired On the second try, I wanted to manually start the bootloader and choose "Recovery mode". Pressing "volume down+power" at first did nothing. Releasing the buttons and then pressing them again brought me into the bootloder. After choosing "Recovery mode", phablet-flash continued and after a while aborted with the following output: INFO:phablet-flash:Wait for recovery image to boot complete INFO:phablet-flash:Clearing /data and /cache INFO:phablet-flash:Pushing /home/till/Downloads/phablet-flash/imageupdates/pool/ubuntu-2b5345658b58e55207c4a4e7b6b3d8cd4f3d9a3187d2448fc9020c884234bac0.tar.xz to /cache/recovery/ failed to copy '/home/till/Downloads/phablet-flash/imageupdates/pool/ubuntu-2b5345658b58e55207c4a4e7b6b3d8cd4f3d9a3187d2448fc9020c884234bac0.tar.xz' to '/cache/recovery/': Permission denied ERROR:phablet-flash:Command 'adb push /home/till/Downloads/phablet-flash/imageupdates/pool/ubuntu-2b5345658b58e55207c4a4e7b6b3d8cd4f3d9a3187d2448fc9020c884234bac0.tar.xz /cache/recovery/' returned non-zero exit status 1 Removing directory /tmp/tmpDnbz6N Removing directory /tmp/tmpth4L6w What can I do to properly flash my phone with Ubuntu Touch?

Should the phone be rooted? This is not mentioned in the instructions.

  • MySQL – How to Find mysqld.exe with Command Prompt – Fix: ‘mysql’ is not recognized as an internal or external command, operable program or batch file

    - by Pinal Dave
    One of the most popular question I get after watching my MySQL courses on Pluralsight is that beginning users are not able to find where they have installed MySQL Server. The error they receive is as follows when they type mysqld command on their default command line. ‘mysql‘ is not recognized as an internal or external command, operable program or batch file. This error comes up if user try to execute mysqld command on default command prompt. The user should execute this command where mysql.exe file exists.  If you are using Windows Explorer you can easily search on your drive mysqld.exe and find the location of the file and execute the above command there. However, if you want to find out with command prompt the location of mysqld.exe file you can follow the direction here. Step 1: Open a command prompt Open command prompt from Start >> Run >> cmd >> enter Step 2: Change directory You need to change the default directory to root directory, hence type cd\ command on the prompt to change the default directory to c:\ . Here we are assuming that you have installed MySQL on your c: drive. If you have installed it on any other drive change the drive to that letter. Step 3: Search Drive Type the command dir mysqld.exe /s /p on the command prompt. It will search your directories and will list the directory where mysqld.exe is located. Step 4: Change Directory Now once again change your command prompt file location to the folder where your mysqld.exe is located. In my case it is located here in folder C:\Program Files\MySQL\MySQL Server 5.6\bin hence I will run following command: cd C:\Program Files\MySQL\MySQL Server 5.6\bin . Step 5: Execute mysqld.exe Now you can once again mysqld.exe on your command prompt. You can use this method to search pretty much any file with the help of command prompt.

  • How to add items to the Document Types context menu.

    - by Vizioz Limited
    I am currently working on an extension to Umbraco that needed an extra menu item on the Document Types menu in the Settings section, my first thought was to use the BeforeNodeRender event to add the menu item, but this event only fires on the Content and Media menu trees.See: Codeplex Issue 21623The "temporary" solution has been to extend the "loadNodeTypes" class, I say temporary because I assume that the core team may well extend the event functionality to the entire menu tree in the future which would be much better and would prevent you from having to complete override the menu items.This was suggested by Slace on my "is it possible to add an item to the context menu in tree's other than media content" post on the our.umbraco.org site.There are three things you need to do:1) Override the loadNodeTypesusing System.Collections.Generic;using umbraco.interfaces;using umbraco.BusinessLogic.Actions;namespace Vizioz.xMind2Umbraco{ // Note: Remember these menu's might change in future versions of Umbraco public class loadNodeTypesMenu : umbraco.loadNodeTypes { public loadNodeTypesMenu(string application) : base(application) { } protected override void CreateRootNodeActions(ref List<IAction> actions) { actions.Clear(); actions.Add(ActionNew.Instance); actions.Add(xMindImportAction.Instance); actions.Add(ContextMenuSeperator.Instance); actions.Add(ActionImport.Instance); actions.Add(ContextMenuSeperator.Instance); actions.Add(ActionRefresh.Instance); } protected override void CreateAllowedActions(ref List<IAction> actions) { actions.Clear(); actions.Add(ActionCopy.Instance); actions.Add(xMindImportAction.Instance); actions.Add(ContextMenuSeperator.Instance); actions.Add(ActionExport.Instance); actions.Add(ContextMenuSeperator.Instance); actions.Add(ActionDelete.Instance); } }}2) Create a new Action to be used on the menuusing umbraco.interfaces;namespace Vizioz.xMind2Umbraco{ public class xMindImportAction : IAction { #region Implementation of IAction public static xMindImportAction Instance { get { return umbraco.Singleton<xMindImportAction>.Instance; } } public char Letter { get { return 'p'; } } public bool ShowInNotifier { get { return true; } } public bool CanBePermissionAssigned { get { return true; } } public string Icon { get { return "editor/OPEN.gif"; } } public string Alias { get { return "Import from xMind"; } } public string JsFunctionName { get { return "openModal('dialogs/xMindImport.aspx?id=' + nodeID, 'Publish Management', 550, 480);"; } } public string JsSource { get { return string.Empty; } } #endregion }}3) Update the UmbracoAppTree table, my case I changed the following:TreeHandlerTypeFrom: loadNodeTypesTo: loadNodeTypesMenuTreeHandlerAssemblyFrom: umbracoTo: Vizioz.xMind2UmbracoAnd the result is:

  • Chuck Norris Be Thy Name

    - by Robz / Fervent Coder
    Chuck Norris doesn’t program with a keyboard. He stares the computer down until it does what he wants. All things need a name. We’ve tossed around a bunch of names for the framework of tools we’ve been working on, but one we kept coming back to was Chuck Norris. Why did we choose Chuck Norris? Well Chuck Norris sort of chose us. Everything we talked about, the name kept drawing us closer to it. We couldn’t escape Chuck Norris, no matter how hard we tried. So we gave in. Chuck Norris can divide by zero. What is the Chuck Norris Framework? @drusellers and I have been working on a variety of tools: WarmuP - http://github.com/chucknorris/warmup (Template your entire project/solution and create projects ready to code - From Zero to a Solution with everything in seconds. Your templates, your choices.) UppercuT - http://projectuppercut.org (Build with Conventions - Professional Builds in Moments, Not Days!) | Code also at http://github.com/chucknorris/uppercut DropkicK - http://github.com/chucknorris/dropkick (Deploy Fluently) RoundhousE - http://projectroundhouse.org (Professional Database Management with Versioning) | Code also at http://github.com/chucknorris/roundhouse SidePOP - http://sidepop.googlecode.com (Does your application need to check email?) HeadlocK - http://github.com/chucknorris/headlock (Hash a directory so you can later know if anything has changed) Others – still in concept or vaporware People ask why we choose such violent names for each tool of our framework? At first it was about whipping your code into shape, but after awhile the naming became, “How can we relate this to Chuck Norris?” People also ask why we uppercase the last letter of each name. Well, that’s more about making you ask questions…but there are a few reasons for it. Project managers never ask Chuck Norris for estimations…ever. The class object inherits from Chuck Norris Chuck Norris doesn’t need garbage collection because he doesn’t call .Dispose(), he calls .DropKick() So what are you waiting for? Join the Google group today, download and play with the tools. And lastly, welcome to Chuck Norris. Or should I say Chuck Norris welcomes you…

  • How to share two keyboard on the same laptop, french iso layout and usa ansi layout keyboard with usb?

    - by reyman64
    I recently buy a "noppoo choc mini" with this specific ANSI US-INTERNATIONAL pc84 layout. This specific keyboard have only 84 key , a 60% (compact tenkeyless) reduced layout My problem is simple, there is no keyboard layout into Ubuntu 12.04 which correspond to this usa normal ansi layout ... so it's the same problem with reduced version and only 84 key .. I search a template of normal ANSI US-INTERNATIONAL for xmodmap/xkb, and after i can try to manually map the other key. I search on google, and i don't find any other user which have same problem, so it's seem i have not the good keywoard to search this information.. Edit 1 : Here you can see there is probably a bug in ubuntu, because the layout for USA with dead key is not correct ! I have this : http://minus.com/lEdKMrsNAwkVA And other users have this for the same layout : http://i.stack.imgur.com/p52XG.png EDIT 2 It seems after a "sudo dpkg-reconfigure keyboard-configuration" : french standard keyboard pc105 + precision M65 keyboard from dell laptop Now i can see the good us layout in parameters, but i cannot have the iso layout for french usage... EDIT 3 Ok, after reboot i understand the probleme, i explain. I have one laptop with integrated french keyboard, and i want to use my usb keyboard which use a usa ANSI layout. It seem it's impossible in ubuntu and "dpkg-reconfigure keyboard-configuration" to share two different physical layout (ANSI and EU ISO) on the same computer ... EDIT4 Ok, it seems i can switch the physical layout (ISO <- ANSI) with this command in terminal : setxkbmap -layout us setxkbmap -layout us -variant alt-intl an setxkbmap -layout fr It's very complicated qnd it seem ubuntu 12.04 have big problem with keyboard manager ... because all works great with these two commands, without ANY change into the system parameters keyboard !!! Second bug ? The image of the layout for fr is buggy, the layout is not ISO, but i can press on the letter "< " at the left of right shift without any problem ! You can see the image here (french alternative with ANSI layout ? it's crazy ?) : http: //minus.com/lXsDJwoeyWAfF Can you help me on this point ? I'm lost with xkb, and manual mapping is very complicated ... Thanks a lot, SR

  • Engagement: Don’t Forget Your Employees!

    - by Kellsey Ruppel
    By Mark Brown, Sr. Director, Oracle WebCenter  This week we want to focus on Employee Engagement, and how it is critical to your business. Today we hear and read a great deal about “Customer Engagement” – and rightly so, it is those customers, whether they be traditional paying customers, citizens, students, club members, or whomever it is that are “paying the bills”.  A more engaged customer is more likely to make it easier to pay those bills by buying more, giving good reviews, or spreading the word of how wonderful their experience was. But what about those who are providing those services, those who design and make those goods; why is it that all too often they are left out of conversations concerning engagement? In fact, it is critical that we consider our employees as customers since they are using internal systems that run your organization the same way customers use external systems. Studies have shown that an organization in which the employees feel “engaged” or better able to make decisions, do their jobs, and are connected to their peers have better return to their stakeholders. (shareholders).  On the surface this seems obvious, happy employees are more productive employees. But it leads to the question – how many of our existing policies, systems and processes are actually reducing that level of engagement? Let’s look at a couple examples. If posting new information that may be of great value to everyone in the larger organization is hard to do because we use an antiquated system, then we’re making it hard to share and increasing the potential for duplicate work. If it is not trivially obvious how to create and publish this post, then chances are very high that I’ll put it on the bottom of my queue. And finally, when critical information is spread across various systems, intranet sites, workgroups and peoples inboxes, then it is very hard to learn and grow from that information.  These may sound trivial, but how often do we push things off not because it is intellectually challenging, we may have the answer at our fingertips, but because it is hard to make that information readily available.  If an engaged employee is a productive employee, then what can we do to increase their level of engagement? We can start by looking for opportunities to provide self-documenting self-service solutions. Our newer employees grew up using simplified web interfaces everyday and they loathe calling a help-desk unless it is the last resort. Sadly, many of our enterprise applications have not kept pace and we all still have processes that are based on sending an email -- like discount approvals, vacation requests, or even offer-letter approvals.   My suggestion is to pick one highly visible, high-impact process where employees are either reticent to execute on the process or openly complain about how cumbersome it is and look at the mechanism for that process. If there are better ways, streamlined steps, better UIs that could be done, then you have a candidate to reconfigure that process and make it more engaging. Looking to better engage your employees? Start here!

  • SQL SERVER – Simple Explanation and Puzzle with SOUNDEX Function and DIFFERENCE Function

    - by pinaldave
    Earlier this week I asked a question where I asked how to Swap Values of the column without using CASE Statement. Read here: A Puzzle – Swap Value of Column Without Case Statement,there were more than 50 solutions proposed in the comment. There were many creative solutions. I have mentioned my personal favorite (different ones) here: Solution of Puzzle – Swap Value of Column Without Case Statement. However, I received lots of questions regarding one of the Solution by SIJIN KUMAR V P. He has used the function SOUNDEX in his solution. The request was to explain how SOUNDEX and DIFFERENCE works. Well, there are pretty decent documentations provided over here SOUNDEX function and DIFFERENCE over on MSDN and if I attempt to explain this function I will end up writing the same details which are available on MSDN. Instead of writing theory, we will try to learn this function by using a couple of simple puzzles. You try to solve the puzzles using the MSDN and see if you can learn something very quickly. In simple words - SOUNDEX converts an alphanumeric string to a four-character code to find similar-sounding words or names. The first character of the code is the first character of character_expression and the second through fourth characters of the code are numbers that represent the letters in the expression. Vowels incharacter_expression are ignored unless they are the first letter of the string. DIFFERENCE function returns an integer value. The  integer returned is the number of characters in the SOUNDEX values that are the same. The return value ranges from 0 through 4: 0 indicates weak or no similarity, and 4 indicates strong similarity or the same values. Learning Puzzle 1: Now let us run following four queries and observe its output. SELECT SOUNDEX('SQLAuthority') SdxValue SELECT SOUNDEX('SLTR') SdxValue SELECT SOUNDEX('SaLaTaRa') SdxValue SELECT SOUNDEX('SaLaTaRaM') SdxValue When you look at the result set all the four values are same. The reason for all the values to be same is as for SQL Server SOUNDEX function all the four strings are similarly sounding string. Learning Puzzle 2: Now let us run following five queries and observe its output. SELECT DIFFERENCE (SOUNDEX('SLTR'),SOUNDEX('SQLAuthority')) SELECT DIFFERENCE (SOUNDEX('TH'),SOUNDEX('SQLAuthority')) SELECT DIFFERENCE ('SQLAuthority',SOUNDEX('SQLAuthority')) SELECT DIFFERENCE ('SLTR',SOUNDEX('SQLAuthority')) SELECT DIFFERENCE ('SLTR','SQLAuthority') When you look at the result set you will get the result in the ranges from 1 to 4. Here is how it works if your result is 0 which means absolutely not relevant to each other and if your result is 1 which means the results are relevant to each other. Have you ever used above two functions in your business need or on production server? If yes, would you please leave a comment with use cases. I believe it will be beneficial to everyone.

    After today's update ubuntu became 2d despite the fact that I logged in under "ubuntu" not "ubuntu 2d". Also some other issues appeared (e.g. my shortcuts rolled back, num pad doesn't work, caps lock key don't have any effect on case, when I'm typing in dash - it doubles every letter - 'n' -- 'nn' ) Here is update log: Setting up google-chrome-stable (17.0.963.83-r127885) ...

  • Qt's future in the light of Nokia-Microsoft partnership

    - by Shinnok
    In case you missed it, a lot has happened in the last two day that could potentially impact the Qt framework, for the worse. :-( It will impact the mobile sector in several and probably not currently acknowledged ways, for sure. It started yesterday with Nokia's CEO Stephen Elop internal letter depicting Nokia sitting on a burning platform and the need for a big and aggressive shift in business. A day later, at the Nokia World conference, Nokia announced the partnership with Microsoft , which at the moment resumes to Nokia adopting the Windows Phone 7 platform and development environment, dumping Symbian along the road and tagging Meego as R&D(a pretty dangerous keyword if you ask me), as for Maemo/N900 series i guess it's bye bye for good. I know what you're thinking but no, Qt is not going to be ported to the Window Phone platform. And i'm also scared about this. You can watch the Elop & Ballmer joint press release here. Now after reading this huge thread on the Qt-interest mailing list i can't help but wonder, what is the future of Qt at Nokia, now that they aren't focused(at all?) on Qt anymore(remember the full focus switch on Qt as main development framework for all Nokia products(including Symbian, yes) back in October?). I love Qt, in my opinion it is the only true cross-platform application development framework and one of the few to make C++ development a joy(to the extent possible) and good things has happened to the framework and considerable momentum while under Nokia, thus i am wondering, what are the chances that Qt might suffer a slow death at Nokia after this? Yes i know about KDE.org and the fact that Qt is easily spawnable, but i still feel uneasy. It also must be horrible for all of the efforts either by Nokia employees or third parties that have gone into Symbian and all of the Ovi Store Symbian/Qt content and business and why not, Maemo/Meego. There are also massive layouts planned, i suspect Symbian techs and Qt? I'd love to hear your input on this? Is Qt future safe&proof? LE: The question as been gradually revised, improved and better referenced, thus you might want to throw a quick re-read to see what you might have missed.

  • Free eBook with SQL Server performance tips and nuggets

    - by Claire Brooking
    I’ve often found that the kind of tips that turn out to be helpful are the ones that encourage me to make a small step outside of a routine. No dramatic changes – just a quick suggestion that changes an approach. As a languages student at university, one of the best I spotted came from outside the lecture halls and ended up saving me time (and lots of huffing and puffing) – the use of a rainbow of sticky notes for well-used pages and letter categories in my dictionary. Simple, but armed with a heavy dictionary that could double up as a step stool, those markers were surprisingly handy. When the Simple-Talk editors told me about a book they were planning that would give a series of tips for developers on how to improve database performance, we all agreed it needed to contain a good range of pointers for big-hitter performance topics. But we wanted to include some of the smaller, time-saving nuggets too. We hope we’ve struck a good balance. The 45 Database Performance Tips eBook covers different tips to help you avoid code that saps performance, whether that’s the ‘gotchas’ to be aware of when using Object to Relational Mapping (ORM) tools, or what to be aware of for indexes, database design, and T-SQL. The eBook is also available to download with SQL Prompt from Red Gate. We often hear that it’s the productivity-boosting side of SQL Prompt that makes it useful for everyday coding. So when a member of the SQL Prompt team mentioned an idea to make the most of tab history, a new feature in SQL Prompt 6 for SQL Server Management Studio, we were intrigued. Now SQL Prompt can save tabs we have been working on in SSMS as a way to maintain an active template for queries we often recycle. When we need to reuse the same code again, we search for our saved tab (and we can also customize its name to speed up the search) to get started. We hope you find the eBook helpful, and as always on Simple-Talk, we’d love to hear from you too. If you have a performance tip for SQL Server you’d like to share, email Melanie on the Simple-Talk team ([email protected]) and we’ll publish a collection in a follow-up post.

  • How to Use Your Android Phone as a Modem; No Rooting Required

    - by Jason Fitzpatrick
    If your cellular provider’s mobile hotspot/tethering plans are too pricey, skip them and tether your phone to your computer without inflating your monthly bill. Read on to see how you can score free mobile internet. We recently received a letter from a How-To Geek reader, requesting help linking their Android phone to their laptop to avoid the highway robbery their cellular provider was insisting upon: Dear How-To Geek, I recently found out that my cellphone company charges $30 a month to use your smartphone as a data modem. That’s an outrageous price when I already pay an extra $15 a month charge just because they insist that because I have a smartphone I need a data plan because I’ll be using so much more data than other users. They expect me to pay what amounts to a $45 a month premium just to do some occasional surfing and email checking from the comfort of my laptop instead of the much smaller smartphone screen! Surely there is a work around? I’m running Windows 7 on my laptop and I have an Android phone running Android OS 2.2. Help! Sincerely, No Double Dipping! Well Double Dipping, this is a sentiment we can strongly related to as many of us on staff are in a similar situation. It’s absurd that so many companies charge you to use the data connection on the phone you’re already paying for. There is no difference in bandwidth usage if you stream Pandora to your phone or to your laptop, for example. Fortunately we have a solution for you. It’s not free-as-in-beer but it only costs $16 which, over the first year of use alone, will save you $344. Let’s get started!

  • A Bad Day at Work

    - by TehGrumpyCoder
    There's lots of ways of having a bad day at work... I suppose for many people, just being *at* work makes it a bad day, but I happen to be one of those people that found a way to do something I like for a living. I've always said "if you're not having fun, what's the point?" ... on the latest Zune podcast, they were interviewing someone from the WP7 team and he said they're mantra is "It's not done until it's fun" ... I like that too. But, even when you're doing what you like for a living, it can get tedious. There were times that I didn't look forward to going out and playing guitar on a Friday or Saturday night, and some nights I was looking at my watch just waiting for it to be over. Well, that was today... like Steve Martin in "The Jerk" ... the first hour was like a regular hour, but then the rest of the morning was like a day, and the afternoon has been like a week. I've got a list of stuff I need to get into my head, and it's tough when the highest technology you have during 9 hours of your day is .NET 2.0 and you can only run what IT installed. I get wrapped around the power take-off reading something and dearly want to write some code to try, but with the state of technology here, it's like trying to teach jazz chords to someone that showed up for their lesson with that stupid plastic guitar from Guitar Hero. I tried to watch a training video... downloaded it zipped so maybe it wouldn't be noticed like it might if I streamed it. Then nothing on this machine would play the video... dang! Well, if someone doesn't take me out on the drive tonight or back in tomorrow, maybe it'll be a better day... or maybe I'll d/l a bunch of training videos in a different format, or bring in a decent viewer, or download them to my Zune maybe... that would work. I suppose at age 61 there are worse things than feeling stifled... for instance, so far I've lived 2 years longer than my father... but at the same time, he's the one that pointed out that in my first letter home from Boot Camp "He's complaining, he's fine"... guess he had my number :) I think he'd appreciate "Teh Grumpy Coder"
